All anglerfish have ability to attract prey, using parts of their bodies as lures.

During one ROV dive, the researchers said, they observed C. coloratus deploying a shaggy, mop-like lure, called an esca, which it dangled from the end of a modified fin near the top of its head.

After an unsuccessful attempt at attracting a meal, the anglerfish stowed its fishing gear away in a special cavity located between its eyes, they said.
